I believe most tags are standardized. Though, from what I can tell its not super easy to parse what group they belong to since there are 1000s of tags. If you used exiftool or something similar when the data is extracted that would probably make it a lot easier. I’d be mainly concerned with the “EXIF” group since it contains basic camera settings. Things like XMP data contain settings from the photo editor used and probably isn’t as useful to most people. Plus, some editors add a ton of data.
I attached an image and the output from exiftool as an example of how it groups different kinds of data. It can export data in different formats (including JSON).
exiftool -s -g -j {input file}
